The bronchial stump fistula (BSF), which is located on the bronchial stump, is a specific type of BPF. BSF can be directly diagnosed via bronchoscopy. However, identification becomes difficult when the BSF is very small (less than 1 mm), referred to as micro BSF in this study because it cannot be found during bronchoscopic exploration. This clinical dilemma easily leads to misdiagnosis of BSF. In this paper, a new procedure for locating micro BSFs using guidewire exploration was reported. This innovative approach involves the use of a guidewire to detect suspected micro BSFs. If the guidewire successfully penetrates the bronchial stump, it indicates the presence of a micro BSF; otherwise, there is none. After precise localization of three micro BSFs, submucosal injection of lauromacrogol around them was performed followed by thoracic fenestration.</p>","PeriodicalId":45846,"journal":{"name":"Respirology Case Reports","volume":"12 12","pages":"e70081"},"PeriodicalIF":0.8,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11613215/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142773424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
